Description

  The present invention relates to the use of certain combinations of insecticidal active ingredients, their compositions, and in particular nematodes in plant propagation material and plant organs growing at a later time by applying the combination to plant propagation material and And / or a method of using such a combination in the regulation or control of pathogenic damage.

  Nematodes damage crops by direct supply damage by transmitting viruses and promoting bacterial and fungal infections. The damage caused by nematodes on crops is generally not specified and is easily confused with drought, malnutrition or disease. Typical symptoms are wilting, yellowing of the leaves, and uneven growth or growth inhibition.

  Methods for regulating nematodes and thereby protecting plants include (1) the use of nematode control agents (eg, aldicarb) and fumigants (eg, methyl bromide), (2) soil vapor treatment Use, (3) use of effective rotation measures against nematodes specific to a particular crop, but nematodes with different hosts that cannot be controlled by this method, and (4) conventional varieties Use of nematode resistant or tolerant crops (genetically modified plants) developed by improved or recombinant DNA technology.

  Certain combinations of nematodes and / or active ingredients for regulating pathogenic damage have been described in the literature. The biological properties of the known combinations are totally unsatisfactory, for example, in the areas of pathogenic regulation, phytotoxicity, and environmental and worker exposure. In particular, improved methods of regulation or suppression are sought when pathogens are resistant or at risk of having resistance to previously known combinations.

  There is a continuing need to provide insecticide combinations that provide improved, in particular, nematode and / or pathogenic damage, eg, biological properties, such as synergistic properties.

Kazusafos, Chloripyrifos, Dimethoate, Etoprofos, Phenamifos, Phosphiazate, Heterophos, Folate, Phosphamidone, Phosphocarb, Terbufos, Triazophos), Fumigant (e.g. Chloropicrin, Dazomet, PCIP, Metam, Methyl bromide, Methyl iodide, Methyl Isothiocyanate) and certain fungicides (eg, benomyl, captan, thiabendazole, thiophanate-methyl). Specific preferred nematode control agents include abamectin, thiodicarb, aldicarb, benomyl, captan, oxamyl, thiobendazole and thiophanate-methyl. More specific preferred nematode control agents include abamectin, siodicarb, aldicarb and oxamyl.

  The term “plant activator” does not mean a compound that acts directly on the disease organism, nor does it mean that it modifies the DNA of the treated plant, but instead is referred to as systemic acquired resistance (SAR). Means a compound that activates a natural defense mechanism in a host plant. Non-limiting examples of plant activators include acibensola-S-methyl, CGA 210007, benzoic acid, harpin, magnesium-dihydrojasmonate and salicylic acid.

  The combinations of the present invention are particularly effective against fungal pathogens of the Fusarium, Psium and / or Rhizoctonia species.

  The combinations of the present invention are formulated for specific uses. Preferably, the combination is formulated to protect the cultivated plant or its propagation material. Advantageously, the combination is formulated for seed treatment applications to regulate or control nematode damage found in agriculture and forests, especially plant damage in the early stages of its onset.

  Furthermore, the combinations of the present invention can be applied to plants and / or plant parts in a conventional manner such as leaf spraying. Accordingly, the benefits obtained from the present invention include (a) treating plant propagation material in combination, or (b) applying the combination to plants and / or parts of plants that grow from plant propagation material, or This is achieved by either (a) or (b).

  Furthermore, the present invention also contemplates the soil application of the combination of the present invention to regulate nematodes and / or pathogens generated from the soil. The method of application to the soil may be via any suitable method that ensures that the combination penetrates the soil. For example, seedling tray application in dredging application, soil immersion, soil injection, drip irrigation, application by sprinkler or central pivot, soil uptake (in wide cast or band) are such methods. Thus, the benefits gained from the invention include (A) treating the plant amplification material in combination, or (B) applying the combination to a site where regulation is desired, generally a plant growth site, or (A) and (B). For example, the combination of the present invention is applied to bare soil in the absence of plants or plant propagation material, which is then advantageously planted on such treated soil. Alternatively, the combination of the invention can be applied to the soil at the same time that the plant propagation material is planted in the soil, for example by sparkling the granular combination. Another possibility is that the plant propagation material is planted in untreated soil and then the combination of the present invention is applied to the plant propagation material site planted, for example by soaking with a solution of the combination. is there. Similarly, the benefits obtained from the present invention include (A) applying a combination to a site where regulation is desired, generally a plant growth site, or (B) combining to a plant or plant part that develops from plant propagation material. Or by applying one of (A) and (B).

  The term “plant propagation material” is understood to mean all occurrences of a plant, for example seeds. This can be used for the propagation of the latter and plant material, such as cutting and tubers (eg potatoes). Thus, the parts of the plant used herein contain propagation material. Examples include seeds (in a strict sense), roots, fruits, tubers, bulbs, rhizomes, plant parts. Also included are germinated and young plants that will be transplanted after germination or emergence from the soil. These young plants are protected before transplantation by total or partial treatment by immersion.

  A plant part and a late-growing plant organ are any part of the plant that grows from plant propagation material such as seeds. Plant parts, plant organs and plants can also benefit from the protection of nematodes and / or pathogenic damage achieved by applying the combination to plant propagation material. In some embodiments, certain parts of the plant and certain plant organs that grow late may also be considered as plant propagation material, which are applied to (or treated with) the combination; Further plant organs that develop from further plant parts and treated parts of plants, and treated plant organs are also nematodes and / or pathogens achieved by application of the combination to certain parts of plants and certain plant organs Benefit from sexual protection. Methods of applying insecticidal active ingredients and mixtures thereof to plant propagation material (especially seeds) or treating with plant propagation material are known in the art and include propagation material dressing, coating, pelleting, and Includes immersion application.

  The active ingredients can be applied to the seeds using conventional processing techniques and machinery, such as fluid bed methods, roller mill methods, rotary static seed handlers, and drum coasters. Other methods such as a spouted bed are also useful. The seeds are pre-sized prior to coating. After coating, the seeds are typically dried and transferred to a size processor for size selection. Such means are well known in the art.

  In a preferred embodiment, the combination is applied to or treated with a plant propagation material in such a way that germination is not induced; generally, the resulting seed has a very high moisture content So seed soaking induces germination. Accordingly, preferred examples of methods suitable for applying (or treating) plant propagation material such as seeds are seed dressing, seed coating or seed pelleting.

  The plant propagation material is preferably a seed. Since it is believed that the method can be applied to seeds in any physiological state, it is preferred that the seeds be in a sufficiently tolerable state so that they are not damaged during the treatment process. Typically, the seeds are harvested from the field; removed from the plant; and become seeds separated from any cob, stem, shell, and surrounding pulp or other non-seed plant material . It is also preferred that the seed is biologically stable to the extent that the treatment does not cause biological damage to the seed. It is believed that the treatment can be applied to the seed at any time between seed collection and seed sowing or sowing process (application to seed). The seed may be treated before or after treatment, or the treatment may be applied during a priming step.

  Even the distribution of the active ingredient and its adsorption to the seed is desirable during propagation material treatment. The treatment includes the active ingredient (s) on the plant propagation material, such as seeds, from a thin film (dressing) of the formulation whose original size and / or shape can recognize an intermediate state (eg coating), then seed Thicker films (eg pellets with many layers of different substances) (eg carriers, eg clay); from different formulations, eg other active ingredients, no longer recognizable in their original shape and / or size Formulas; polymers and colorants).

  Seed treatment occurs for unseeded seed, and the term “unseeded seed” refers to any period of seed harvesting and seed sowing in the soil for germination and plant growth purposes. Intended to contain seeds.

  Treatment of unsown seeds does not include that practice where the active ingredient is applied to the soil, but is intended to include any application practice that targets the seed during the process of plant growth.

  Preferably, the treatment takes place before sowing of the seed so that the sowed seed is pretreated with this combination. In particular, seed coating or seed pelleting is preferred in the treatment of the combination of the present invention. As a result of the treatment, the active ingredient in the combination is adsorbed on the seed and is therefore available for nematode control.

  The treated seed is stored, treated and grown in the same manner as any other active ingredient that has treated the seed.

  The combination according to the invention consists of crop plants: cereals (wheat, barley, rye, oats, corn, rice, sorghum, rye wheat and related crops); beets (sugar beets and feed beets); Beans, lentil, peas, soybeans); oil plants (rapeseed, mustard, quinola, sunflower); cucumber plants (mallow, cucumber, melon); fiber plants (cotton, hemp, cannabis, jute); vegetables (spinach, lettuce, Suitable for asparagus, cabbage, broccoli, cauliflower, carrot, onion, tomato, pepper, potato, paprika); and ornaments (flowers, shrubs, hardwoods, and evergreens such as conifers). Particularly preferred are cotton, corn, soybeans, sugar beet, cucumber plants and vegetables. Soybean is most preferred.

  Suitable target crops also include the aforementioned types of transgenic crops. Transgenic crops used in accordance with the present invention are plants, their propagation material, known to be obtained from, for example, invertebrates that produce toxins, in particular arthropoda, or Bacillus shringiens In such a way that it is possible to synthesize selectively acting toxins obtained from cis (Bacillus thuringiensis) strains or known from plants such as lectins; or with herbicidal or bactericidal resistance In an alternative method that can be shown, it is transformed by means of recombinant DNA technology. Examples of such toxins or transgenic crops capable of synthesizing such toxins are for example EP-AO 374 753, WO 93/07278, WO 95/34656, EP-AO 427 529 and EP-A- 451 878, incorporated herein by reference.

  Therefore, the plant propagation material treated by the combination of the present invention is resistant to nematodes and / or pathogenic damage; therefore, the present invention is a nematode resistant plant treated with the combination. Propagating material is also provided so that at least the active ingredient is adsorbed to the propagating material such as seed.

  Seed treatment combinations and compositions may contain further active compounds and may be applied together and / or sequentially with further active compounds. These further compounds may be other insecticidal active ingredients, fertilizers, antioxidants or trace element donors, or other preparations that affect plant growth such as inoculum.

  A single insecticidal active ingredient may have activity beyond the field of disease or pest control. For example, pesticides have the activity of fungicides, insectides and nematocides. Specifically, aldicarb is known for its activity as an insecticide, acaricide and nematode, while Metam is known for its activity as insecticide, herbicide, fungicide and nematode. Thiabendazole and captan can provide nematode and fungicidal activities, and thiodicarb is known to have insecticidal and molluscicidal activities.

  The combination of the present invention may be mixed with other pesticides such as fungicides and insecticides.

  Suitable examples of bactericides include bamate fungicides (e.g. thiram), carboxamide fungicides (e.g. carboxin), phenylamide fungicides (e.g. metalaxyl, mefenoxam), phenylpyrrole fungicides (e.g. fludioxonil), Built-in fungicides (eg, azoxystrobin, fluoxastrobin, trifloxystrobin), triazole fungicides (eg, microbutanyl, ipconazole, triadimenol), and mixtures thereof.

  Suitable examples of insecticides include neonicotinoid insecticides (eg clothianidin, imidacloprid, thiamethoxam), pressroid insecticides (eg lambda-cyhalothrin, beta-shifthuslin), benzoylurea insecticides (eg triflumuron), and Including the mixture.

Test description:
1. Soybean cultivated soybean planted in a “cone-tainer” containing a mix of 70% sand and 30% clay loam (1 soybean seed / 1 container) (3.8 cm cell size; 14 cm cell depth; Ray Leach 'Cone-tainer' Single Cell System consists of individual cells that can be arranged in a tray and available from Stuewe and Sons) (one soy seed / container). The container was filled with 10 cm x 10 cm pieces of cheesecloth on the bottom to prevent soil from coming out of the bottom. The soil mixture was heat sterilized for 60 minutes before use. An extra container was planted, which allowed similar soybean plants to be selected and placed in a randomized full block with 3 repeats for each treatment. The vessel was placed in the growth chamber at 27 ° C. for a 14 hour light period. Growth chamber temperature was monitored at 15 minute intervals using a monitoring data collector. The plants were watered daily to ensure that excessive water supply did not generate nematodes and soak them. The water source was supplemented with fertilizer to promote plant growth.

2. Preparation soil egg inoculation material is "HG-type" 2.5.7 ( "HG-type" test of soybean cyst nematode (Heterodera-Gurishinsu), the soybean cyst nematodes "hetero de la glycine scan, HG" group how Is a greenhouse test that provides information on how well it can be produced in a particular soil). Soil was added to water and poured into 25 mesh sieve or 60 mesh sieve to collect cysts. The soil solution was collected on a 60 mesh sieve and then placed on a 120 mesh sieve over 500 mesh sieve. The rubber stopper was taken and the soil solution was rubbed on a 120 mesh sieve to break the cysts and release the eggs. The egg solution was then centrifuged at 2100 rpm for 2 minutes at a water sugar concentration of 453.6 grams / liter to remove solid debris. The clear egg solution was then centrifuged to obtain a solution of 6,000 eggs / mL.

3. Soybean plant inoculation and cultivation Soybean plants were inoculated with eggs of 6,000 soy cyst nematodes on the 7th day after planting in the container. Plants were inoculated by placing 2.5 cm pencil chips in the soil next to the seedlings. 1 mL of egg solution was pipetted into the hole. Water from the injection bottle was used to crush the soil into the inoculation site. This was used to prevent the soil from hardening and to prevent air pockets from forming in the soil. The inoculated plants were placed in a growth chamber set at 27 ° C. for a 14 hour light period. Growth chamber temperature was monitored at 15 minute intervals using a monitoring data collector. The plants were watered daily to ensure that excessive water supply did not generate nematodes and soak them. The water source was supplemented with fertilizer to promote plant growth.

4. Determination of the number of soybean cyst nematode eggs 30 days after inoculation Plants were removed from the growth chamber 30 days after inoculation to evaluate nematode regeneration factors. The soil and roots of each container were washed to extract cysts. Nematode eggs were isolated by the same method as described in 2 below. The total number of soybean cyst nematode eggs present in each sample was determined. The average value from 3 replicates for each treatment was used for the following calculations.
